Abstract
A fluid device includes: a flow path through which a fluid flows; and an ultrasonic wave application device including an ultrasonic element that transmits an ultrasonic wave, in which the flow path has, as flow path wall surfaces, an ultrasonic wave application surface that applies, to the fluid, the ultrasonic wave transmitted from the ultrasonic element, and a reflection surface that reflects the ultrasonic wave applied to the fluid from the ultrasonic wave application surface, and the reflection surface has a concave curved surface shape.
